The Biggest and The Longest Animals

Which are the biggest and the longest animals of the world? Here is the answer to your question! We have a comprehensive chart with many records for you.

Length + Height = Size

The longest animal is not necessarily the biggest. The elephant, for instance, can get more than 22.9 ft (7 m) long but “only” 12.99 ft (3.96 m) high. You have to consider the height and the length of an animal to find out which one is the biggest. Therefore, the giant ribbing worm Lineus longissimus is not the biggest animal either – even though it can reach a length of 180.4 ft (55 m) according to the Guinness Book of World Records. Its body only measures 0.19 - 0.39 inch (5 – 10 mm) in diameter. And it does not weigh several tons.

The Blue Whale Is the Champion

The blue whale is the biggest animal, because in addition to its length of more than 108.2 ft (33 m) it has a huge circumference and a very heavy body.

*** The polar bear and the Kodiak bear are almost equally long. Therefore both of them are categorized as the longest animals of prey.

They Cannot be Overlooked!

Sperm whale, giant squid, the giant ribbing worm L. longissimus and particularly the blue whale are among the longest animals. Yet, there are also animals that are not as long but rather tall, such as the giraffe.

If you feel dizzy when looking down a 16.4 ft (5 m) springboard, you get an idea of how things look like from a giraffe’s perspective. Luckily the giraffe is used to hold its head high.

By the Way: The Tallest Human Being

An average adult male human being is about 5.8 ft (1.78 m) and a woman about 5.41 ft (1.65 m) tall (people generally were about 3.9 inch (10 cm) smaller in the Middle Ages). But people can get much taller than this. The tallest human who has ever lived ... was 8.92 ft (2.72) m tall. At the age of 10 he already was 6.56 ft (2 m) tall. His name was Robert Wadlow and he lived in the USA from 1918 - 1940. The tallest woman of the world was Trijntje Keever from Holland. She was 8.36 ft (2.55 m) tall and lived from 1616 - 1633.
